ESP32 Forum

Hi, I have a library for inter task communication that uses FreeRTOS queues, but I need to know if it was called from inside interrupt to call the right function. Under STM32 I can use this:
if ((SCB->ICSR & SCB_ICSR_VECTACTIVE_Msk) != 0)

Is there something similar under ESP32 ?

Thanks
Frank

Yes, there's a FreeRTOS function called xPortInIsrContext() which returns true if the calling CPU is inside an ISR.
